How do you avoid ban on pserver v83

Ok I'm not sure where to post this so can a mod move this to the right place thanks. Ok one day I was damage hacking at Zakum and it was almost dead then I D/C and it says my IP has been blocked from connection, but I don't know why Gm’s in p servers are so stupid. If they IP ban you can just change your IP and play again like I'm doing now. When I got banned it said [Message from server] Armed (2750) High Damage.275 what does that mean?. If you don’t understand what I’m talking about here’s a picture:
Is there a way to get passed that [Message from server] on the Gm’s screen?. If you can do that you can hack and never get banned.
